We started and incubated 36 eggs back in August through two times of hatching. So the 2 different flocks are 21 days apart. They all did fine with introducing back then.Some didn't hatch, others hatched, but didn't survive. But we are now left with 23 within those 2 batches. So here are my questions: 1. We have another flock of 9 hens (no roosters) that is about 1 1/2 years old and are in a different chicken coop. I would like to start introducing them to this flock in order to utilize the two hen houses. What type of tips can people give me? When I introduced the others it was no big deal and everything went fine. I am noticing the rooster in the 23 flock is starting to do his thing... and I would prefer to take some of them out of there to distribute them a bit better. 2. What is the recommeded feeding for chickens. If I move the 3 monthers in with the 1 1/2 year olds should I put both types of food in the hen house? The 1 1/2 year olds are still laying about 3 to 4 eggs a day between all 9 of them. I would appreciate all advice. Thanks!
